Normally none but if it's an isosceles trapezoid it has one
It has 10 interior angles that add up to 1440 degrees

It has two lines of symmetry, one each perpendicular to each other passing thru the center of the rectangle

When you rotate a shape less than 360 degrees it will look the same. for example a square has rotational symmetry of 4 because it can be reotated 4 time (over 90 degrees) and it will look the same.
Rhinoceroses have like all vertebrates, have bilateral symmetry.
